I've started a Savannah project for XBoard/WinBoard. My plan is to copy the sources off my home machine, where they currently live under RCS, into the CVS repository on Savannah. This should enable others to join the project and integrate their own code contributions, instead of having to email them to me and wait forever for me to get around to doing something with them.

If you're interested in contributing to the project, please let me know. Because XBoard is a GNU project with copyright owned by the FSF, you'll need to fill out FSF's standard dead-tree paperwork to contribute your changes.
